Bobby Singh's Audi S2 avant project

I'm tempted by the TFSI coils, but I'm trying to keep the car as standard as possible. However I guess at some point I will have to convert. As I not sure you can even buy the old style coils anymore.

Best thing I done - I was changing plugs etc and the issue would go away for a bit, but since doing the TFSI coils no more issue. Power is smoother without any holding back or misfiring.
I understand there is something about keeping the car original, but if parts hard to find you will only end up installing used parts which are 27 years old plus wiring around heat sources is totally weak.

As mentioned previously I will do the injector wiring next - last thing I want is a lean event after spending 000's on the engine.

Had the front bumper off to take out the headlights as I had a spare plug not connected - turns out someone previously fitted headlights without level adjustment motors.
Would have been nice to fit them but they are pretty rare to find and the ones I have look brand new.

While the bumper was off I noticed the Fan resistor looked pretty poor and the connections looked worse.

Cleaned up well enough

No more clicking and a very easy job so now ordered the other side too :)

More parts arrived:

- Injector wiring loom repair items
- Sump baffle plates
- light single mass flywheel
- Nuts, bolts and studs

Have had this annoying fault with the doors not staying open and end up smashing in my leg when getting out. Looks like the bottom hinge is spring loaded and rides two cams.

New hinges are 120 euros etc from AT - managed to get all 4 doors complete with hinges, rubbers, windows, motors, mirrors etc for a very good price.

Haven't got pics but the hinges for the front doors are now changed and working well - nice to have doors that stay in place.

Tricky part is the adjustment but I found measuring the old hinge (has a big hex for adjustment behind the bolt) got me 95% there and then used a jack to lift the door with the 4 bolts on the slackened off.

Next the new engine and all the rest of the parts are at the machine shop

They will bore the block using the torque plate
Keeping in mind the piston to wall clearence of 0.10mm

Everything will be balanced, washed and cleaned
I've asked to them machine the crank nose surface to ensure its true.

Ring gaps 0.40 top 0.45 second

Finally skim the deck.

In other news I bought a 7a head had it converted for turbo use, but it seems someone the past had repaired the exhaust stud thread and gone through:

Baffle plates still need to be welded but in I've been making progress in other area's

Speedo stopped working
Checked the wiring and could not see any issues.
Ended up changing the speed sensor and reflowed the joints and seems be working again:

Front pulley bolt:

So the pulley and crank (diesel) requires a longer bolt, just for information I mailed Febi and they confirmed this as a 11.9 tensile.
I later got the item from TPS which I suspect is 11.9
Stock ABY - 65mm long 12.9
Diesel AEL - 110mm long 11.9

So the seller of the head didn't want to replace or repair the head so decided to get it done myself.

Great work, That's a really professional fix for that issue on head. Most people would have just drilled a slot in the manifold and left it at that. Those ring gaps look quite small is that stock ring gap numbers?

The only thing that didn't need any balancing was the flywheel
Sachs clutch, cranks fluid filled pulley etc all needed balancing
Is this your handy work or a company?

Thanks Karl - trying to do the best job possible for this motor
Stock ring gap is 0.15 to 0.35mm with wear limit at 1mm

Well it was going too smoothly right.
Went to put the crank in and tighten up the mains to 75nm (recommended settings for the 12.9 bolts) and the crank got tight.
Measured the journals from the S2 crank to the Diesel and they were 1:1
Measured the bearings all ok there too.
Put the S2 crank in with old bearings and old bolts at 65nm and the crank turned but still not that free.

Went back to the machine shop and they measured the journals with a bore gauge and noticed the bore was getting tight after torqueing the bolts down.
Its looking like I need line boring done to fix this.

In the meantime found out that 1.9PD (ARL) mains bolts are 12.9 & 80mm long (same as the S2 ones) which have a torque setting of 65nm plus 90deg.
So line boring will be done with diesel bolts next.
Mains bolts diesel bolts are N90889701 rated at 12.9

Its never straight forward

That's very strange about the main caps Bobby. Have to ask the question, you did have them in the correct order and the correct orientation. I am sure you double checked everything. I use the 12.9 PD main bolts in my 1.8T. The stock 1.8T mains are 10.9 and the 2.0 TFSI use the same bolts as the PD150.

Hey Karl I got a sneaky feeling the vinegar has attacked the surfaces when I cleaned the block up. Once the attached area is cleaned up it should be fine - but its just my theory without any evidence.

Is this just a trickle charger Bobby? Straight forward to use? I need to invest in something for my B5, it often struggles when I don’t drive it for 3/4 weeks at a time.

That's exactly what it is - nice and small approx £40 from Halfords

Engine building round 2
So the block is back from the line honing and crank was spining freely.
When the bearing clearance was measured again it was noted one journal was alittle tight @ 0.025mm.
It was decided to grind the crank a little.

Progress:
